Calling ioctl() to re-read partition table. Re-reading the partition table failed.: Resource busy The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8). root@OpenWrt:/# reboot |

After reboot, format /dev/mmcblk0p3, /dev/mmcblk0p5, /dev/mmcblk0p6 and /dev/mmcblk0p6 mmcblk0p7 as ext2 partitions.
